Description
The Superchips Flashcal (PN 3571-JL) is the ultimate plug-and-play options-control device for the 2018–2025 Jeep Wrangler JL (2-door and 4-door) with the 3.6L, 2.0L Turbo, or 4xe powertrain. It connects through your OBD-II port and lets you correct and customize dozens of factory settings with simple yes/no selections — no programming experience needed.
Recalibrate your speedometer for oversized tires (up to 37″), adjust gear-ratio settings, fine-tune TPMS thresholds front and rear, and take control of lighting (daytime running lights, fog-with-high-beam “Bambi Mode”), auto start/stop, and a range of convenience features. Rubicon owners also get sway-bar and axle-locker controls. When you’re ready for power, the Flashcal can be upgraded online to a full Flashpaq tuner.
